In each of the forms shown in the drawings the coarse adjustment is made by manipulation of the levers. After this adiustment has been r'nade a finer adjust-ment is made in the V formsliown in Figure 1 by rotating the head y20 to lrotate the rod and to move the clevis longitudinally, thereby 1'otating the plate.

In the form shown in Figure 5 the rotation of the head will cause the Vernier longitudinally of the lever and carry with it the rod 30, which does tudinally. The longitudinal movement of the rod 30 will cause the plate to rotate, and thereby shift the arm 13. f

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention. l

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

' 1. In a control unit, a frame having a hub, a lurality of hollow levers, each lever being bifurcated at one end to form spaced arms with holes therein to receive the liub, a plate for each lever mounted on the hub between the arms, and longitudinally movable means on each lever forming a connection between each plate and its lever, and means rotatably mounted in each lever for moving said means longitudinally; whereby the plate may be rotatedon the hub by moving the lever and may be rotated on the hub independent of any movement of the lever.

2. In a control unit, a frame having a hub, a

plurality of levers, each lever being bifurcated at one end to form spaced arms with holes therein to receive the hub, a plate for each lever mounted on the hub between the arms, and a connection be' tween each plate and its lever, whereby the plate may be rotated on the hub independent of any movement of the lever, said connection comprising a clevis connected at one end to the plate, 'a rod threaded at one end into the clevis and rotatably supported by the lever, and means on the other end of the rod for rotating the rod.

3. In a control unit, a frame having a hub, a

lever having one end bifurcated to form spacedl arms with holes therein to receive the hub, a plate having a hole therein to receive the hub mounted on the hub between the arms, a pair of arms on the plate, longitudinally movable means on the lever connecting the lever to one plate arm for rotating the plate by moving the lever, said means comprising a clevis attached to the arm v lever and connected wheel to move not rotate but moves longii and a rod rotatably-mounted on' the leverzand threaded into the clevis operable to rotate the plate independent of any movement of the lever.

4. In a control unit, a frame having a hub, a hollow lever having a large end bifurcated to form spaced arms with holes therein to receive the hub, a plate having a hole therein toreceive the hub,mounted on arm, a, rod mounted in the at one end to the clevis, and means connecting'the rod to the lever, whereby one end to one plate the plate may be rotated by moving the lever or yby the ,leven rod independent of any movement of the 5.y In a control unit, a quadrant frame, a supporting shaft, a lever mounted on said shaft comprising a vertically 'disposed portion and a diagonally disposed portion, a second lever mounted on said shaft comprising a pair of angularly disposed arms, and means connected to one of said arms and adjustably carried by the diagonally disposed portion of relationship between said arms and'saidflever.

6. In a control unit, a quadrant frame,l afsjup-` porting shaft, a lever mounted on said shaft com# prising a vertically disposed portion and a vdiagonally disposed portion, a second lever mourited on said shaft comprising a pair of angularly disposed arms, and means connected to one of said arms and adjustably carried by the diagonally disposed portionof the lever for adjusting the relationship between said arms and said lever, said means comprising a rotatable adjusting screw and means for actuating said screw mounted on the head of said diagonally disposed portion Vof the lever.

7. In combination, a quadrant, a lever pivotally mounted on said' quadrant comprising a vertically disposed portion and an angularly disposed' sleeve, a rotatable rod mounted in said sleeve having an actuating head thereon mounted on the end of the sleeve portion of said lever, an angularly disposed lever pivoted with respect to the first-mentioned lever, and means connecting 'the lever whereby it may be adjusted with respect to the first-mentioned lever as to the angular position therebetween and may be bodily moved with the -rst-mentioned lever in its adjusted position.
